The response spectra for the Faiyum earthquake were selected as the best earthquake for the most effective zone near Abu Serga church to construct the design response spectrum for the church. The original acceleration time history was recorded 10 km away from Abu Serga church over the bedrock of Cairo city at Mokattam area (about 10 Km from Abu Serga church). This is considered to be the first response spectrum done for all earthquakes that ever affected Egypt. Fortunately, this earthquake is regarded as one of the most important earthquakes that affected Egypt in the last 100 years. The maximum acceleration response spectrum maintained for Abu Serga church for the church's fundamental resonance frequency, which is 5.5 HZ, is about 100 cm/sec2 for 5% damping. As for the other resonance peaks for the 2nd wooden floor and the roof, nearly the same spectral acceleration occurs (0.1 g).
